The top of the Operator Portal indicates several metrics to provide users with visibility into how the subject Line is performing, both across the Shift and for the Week to Date. While the center metrics in this table are populated according to the Production Statistics enabled in the Production: Settings screen, there are five values that remain fixed on the page, as shown below:
Run Rate
Run Rate: represents the demonstrated throughput of product of the Line; it shows the frequency in seconds at which a unit of product is created by the subject Line. Run Rate can be seen in the Production Run Rate Trend report and Product Order Status dashboard. It also appears as a component of the Performance per Part (PPP %) metric and also the Overall Equipment Effectiveness (OEE) metric.
Definitions and Calculations
Run Rate = (Planned Production Minutes - Downtime Minutes) * 60 / (Actual + Defects)
- Planned Production Minutes represent time that a Line was planned to produce product; this is represented by planned production minutes within active pitches.
- Downtime Minutes represent production time lost to down events; these are calculated from Down (red) dispatches open against a Line during the pitch(es) for the time period of interest.
- Actual represents the quantity of good product produced on a Line for a period of time.
- Defects represent the quantity of bad product produced on a Line for a period of time.
The Line Pitch Board (Production > Pitch Board) contains the information required to calculate Run Rate. On the Pitch Board and on the Operator Portal, the Run Rate on the Line for the Current Shift and the Week to Date are shown in seconds [number of seconds at which a product unit must be produced].
Multiple-Pitch Calculation
Example Data: Each row is data for a pitch; data acquired from the Pitch Board is in white; calculated values are in yellow.
- Run Rate all Pitches = {[SUM(Planned Production Minutes all Pitches) - SUM(Downtime all Pitches)] * 60} / [SUM(Actual all Pitches) + SUM(Defects all Pitches)]
- Run Rate all Pitches = [(635 -206) * 60] / (449 + 15) = 25740 / 464 = 55 s
Under Production: Settings, the Precision of Production Numbers Default dictates the number of decimal places shown for Takt Time on the Operator Portal.
Takt Time
Takt Time: represents the frequency in seconds at which the Line must produce parts to meet customer demand.
As Takt Time is driven by demand and therefore the production schedule, it can be used as a means of comparison for actual production Run Rate or throughput to assess attainment. Takt Time can be seen in the Production Run Rate Trend report. It also appears as a component of the Earned Hours (E-Hrs) metric.
Definitions and Calculations
Takt Time = (Planned Production Minutes * 60 )/ Demand
- Planned Production Minutes represents time that a Line was planned to produce product; this is represented by planned production minutes within active pitches.
The Line Pitch Board (Production > Pitch Board) contains the information required to calculate Takt Time. On the Pitch Board and on the Operator Portal, the Takt Time on the Line for the Current Shift and the Week to Date are shown in seconds [number of seconds at which a product unit must be produced].
Multiple-Pitch Calculation
Example Data: Each row is data for a pitch; data acquired from the Pitch Board is in white; calculated values are in yellow.
- Takt Time all Pitches = {{SUM(Planned Production Minutes per Pitch) * 60]/ SUM(Demand per Pitch}
- Takt Time all Pitches = (635 * 60) / 635 = 60
Under Production: Settings, the Precision of Production Numbers Default dictates the number of decimal places shown for Takt Time on the Operator Portal.
Pace and Pitch Pace
Pace: represents the difference between Actual and Demand, as a means to indicate how many parts ahead or behind a Line is on production.
- Calculation: (Actual - Demand)
Pitch Pace: represents how many pitches a line is ahead or behind
- Calculation: (Actual-Demand) / (Average Demand To Date)
The Pace metric will be the same color as the Pitch Pace metric. The Pace and Pitch Pace metrics may be calculated using a different date range than the date range that is selected on the Production Status by Line dashboard:
- When Day to Date is selected, the Pace and Pitch Pace metrics will be calculated for the selected day, just like all other metrics on the dashboard.
- When Month to Date and Week to Date are selected, and the "Pace Start Date" setting is enabled in the Line Setup screen, the Pace and Pitch Pace metrics will be calculated using the "Pace Start Date" setting as the start date, and the dashboard end date as the end date. We enforce a three-month maximum to calculate Pace and Pitch Pace, so if the "Pace Start Date" is more than three months in the past, we will start counting Pace and Pitch Pace from 3 months ago.
- If there is no "Pace Start Date" set on the line, and if the Production Setting "Carry over the previous week Pace metric" is enabled, the Pace and Pitch Pace metrics will be calculated starting from the previous week's production start of the day.
